Piezoelectric Acoustic Modules

KEMET's multilayer piezoelectric bimorph actuators are ceramic elements used to convert electrical energy into mechanical energy, such as displacement or force, by utilizing the piezoelectric longitudinal effect. KEMET’s piezoelectric acoustic modules use multilayer piezoelectric bimorph actuators, which are produced based on KEMET's unique element structure design and piezoelectric ceramic materials with high electrostrictive factors. The piezoelectric acoustic module generates both sound and vibration from the chassis simultaneously. Typical applications include smartphone receivers and speakers.
